Last updated: 02/17/2009
Urine is normally carried from the kidneys to the bladder via a pair of long, narrow tubes called ureters (each kidney is connected to one ureter). A ureter may become obstructed as a result of a number of conditions including kidney stones, tumors,...
blood clots, postsurgical swelling, or infection. A ureteral stent is placed in the ureter to restore the flow of urine to the bladder. Ureteral stents may be used in patients with active kidney infection or with diseased bladders (e.g., as a result of cancer or radiation therapy). Alternatively, ureteral stents may be used during or after urinary tract surgical procedures to provide a mold around which healing can occur, to divert the urinary flow away from areas of leakage, to manipulate kidney stones or prevent stone migration prior to treatment, or to make the ureters more easily identifiable during difficult surgical procedures. The stent may remain in place on a short-term (days to weeks) or long-term (weeks to months) basis.

Definition
Ureteral stents are thin catheters threaded into segments of the ureter that carry urine, produced by the kidney, either down into the bladder internally, or to an external collection system. Insertion is most often done through the skin (percutaneously); however, in the presence of kidney or ureteral stones, stenting is ideally done during cystoscopy.
